In other words, how would Keaton's Batman function and cope in the "Joel Schmaucherverse" version of Gotham City (with Jim Carrey's Riddler, Tommy Lee Jones' Two-Face, Arnold Schwarzenegger's Mr. Freeze, Uma Thurman's Poison Ivy, and Jeep Swenson's Bane)? Likewise, how exactly would Val Kilmer's Batman function and cope in the "Tim Burtonverse" version of Gotham City (with Jack Nicholson's Joker, Danny DeVito's Penguin, and Michelle Pfeiffer's Catwoman)?
